ANTHONY ISKE AND ALBERT ISKE, OF LANCASTER, PENNSYLVANIA.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 253,868, dated February21, 1882.

, Application 'inea November 1, 188i. (No modela To all whom it mayconcern:

Be vit known that we, ANTHONY IsE and ALBERT IsKE, citizens of theUnited States of America, residing at Lancaster, in the county ofLancaster and State of Pennsylvania, have invented certain new anduseful Improvements in Motors; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertainsto make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

This invention relates to motors which operate by the shifting ofinclosed volatile liquid in 'vacuo from one chamber to another andhigher chamber under the iniiuence of heat and its own gaseous pressureand by the gravin the same line, which improvement consists in thecombination of an oscillating tube having at each end a receptacle forvolatile liquid with acaloriic chamber or chambers into which thesereceptacles dip alternately.

The invent-ion further consists in providing each end of said tube witha.cover which extends over the receptacle at that end and which closesthat side ofthe caloritlc chamber as said receptacle descends into it,thereby prevent ing waste of heat.`

The invention further consists in providing the calorifc chamber with agate or analogous device and connecting the same with the os cillatingtube aforesaid in such manner that the descent of either receptaclecauses said gate to cut off the hot air entirely from the otherreceptacle and give the full effect of the cnr rent to the descendingone.

The invent-ion consists, finally, in certain pealamp, B, or othercalorilic device.

culiarities of combination and construction of the devices hereinafterset forth. A

In the accompanying drawings, Figure 1 represents a rear perspectiveview of ourimproved motor embodying the presentinvention. Fig. 2represents a vertical section of the same, taken longitudinally throughthe axial line of the tube. Fig. 3 represents a front elevation, showingthe pump-operating mechanism.

The same letters of reference designate the same part-s in all of theabove figures.

.A designates a hollow casing, preferably of metal, which constitutes.the supportin g-frame for the motor and also incloses the caloricchamber. This casing is open at the bottom and also at each of its uppercorners, these upper openings forming entrances a a for each of thereceptaclesv hereinafter described. In the front of said casing, atthebottom thereof, is a door, iA', for the insertion and removal of A V-shaped partition, A2, converging downward from the top of the casin gtoward the lamp, divides the caloric chamber into two diverging passagesor apartments, one extending from the lamp to entrancea and the other to.en trance a. On thek top of said casing aretwo standards, C C, whichafford bearings for truun io ns c c', that are formed with Ya sleeve, D,rigidly secured on the middle part of a tube, E.

This tube is of' sheet metal or other stift' material, and has at itsends cylindrical recepta- The heat is thus prevented from escaping, and

also is reflected upon the top of said receptacle.

Trunnion c, before referred to, carries in front of its standard C agear-wheel, G, which meshes with two racks, H H, formed. on the upperends of piston-rods I I, which operate in pump IOC) cylinders J J,supported on a ledge, j, attached to the front of casing A. Of courseany other form of mechanism may be operated instead of these pumps bysaid cog-wheel and pinion or by cranks or other suituable devices.

The other trunnion, c', which, if desired,'may be in one piece withtrunnion c, forming a continuous shaft,) carries a crank-arm, 7c, whichis connected by a long rod or pitman K to a erank-arm, l, on arock-shaft, L, journaled in the front and rear walls of said casing A.This rock-shaft carries a depending gate, M, which Vibrates from side toside as the tube E oscillates on its trnnnions or transverse shaft.

rlhe operation of the machine is as follows: When receptacle E is withinthe calorific ch ainber and receptacle E2 at its highest point the gateM is in position to direct the entire body of heated air against theformer receptacle. The liquid in this receptacle becomes partlyvaporized 5 but as the end of the tube E is extended nearly through thisreceptacle the vai porized liquid is obliged to drive by expansion theremainder ot' the liquid before it through said tube in order to ndroom. This results in transferring bodily and almost instantly the wholesupply of fiuid from the lower receptacle to the upper one. The latterthen preponderates, and therefore descends to becomethe lower in itsturn. During this descent the trnnnioucranks and connecting-rod orpitman v 'above described cause shaft L to rock in the oppositedirection, so that the gate M cuts oft' the hot air from entrance a andallows it to flow to entrance a. Receptacle E2 then passes within orthrough said entrance containing the alcohol, again liquefied bydescending through scribed in the second of our earlier patentshereinbefore referred to.

Of course other forms of cut-olf. mechanism maybe substituted for thegate above described and its operating shaft-cranks and pitman. It is,however, a very convenient and satisfactory device for the purposedesigned. Hot water may be substituted for hot air as a means of partialvaporization.

Of course the receptacles may be duplicated, or the tube, or both.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. An oscillating tube having at each end a receptacle for volatileliquids and a cover, in combination with a caloritic chamber providedwith an entrance for the admission ot' said receptacles, each entrancebeing adapted to be closed by the appropriate cover after the receptaclehas entered.

2. In combination with an oscillating tube and a pair of receptacles forvolatile liquid, attached to the ends of said tube, a calorific chamberdivided into two parts or passages, and a gate or valve within saidchamber connected to said tube in s uch manner that the oscillation ofsaid tube cuts off the hot air from one of said parts or passages anddirects it into the other.

3. In combination with tube E and terminal receptacles E' E2, the casingA, the gudgeons or pivot-shaft for said tube, rock-shaft L, gate M, andthe cranks and pitman or connectingrod, whereby the oscillation of saidtube is enabled to automatically control the vibration of said gate,substantially as set forth.

In testimony whereof we aix our signatures in presence of two witnesses.
